Are β and θ in radians in the Scherrer formula?

Hi
I have several doubts sen Scherrer formula for calculating the size of the crystal

D=0.9λ/βcosθ

β is in radians?

θ is in radians?

Thanks

Hi luciomex,

beta is in radians but teta is in degrees because the dimension of cos(degree) is radians.

Ciao
